At slightly less power, you can get away with the +30% injectors: https://store.katechengines.com/high...s-30-p561.aspx
For example, in my E85 C7 Z06 I have +30% injectors, 38% cam lobe with stock DI pump, and a low side fuel system. That made 760rwhp.


What are your thoughts for those of us with the LT4 LPFP, LT4 HPFP and the JMS voltage booster. Would the +30 or +45 injectors on the stock cam allow us to run more than the E50 some of us run now?
